Form W-4P

Form W-4P is the withholding certificate for payments that arrive on a schedule from a retirement source: a pension, an annuity, a profit-sharing or stock bonus plan, or an individual retirement arrangement paying in installments. The IRS's description is direct: "Complete Form W-4P so your payer can withhold the correct amount of federal income tax from your periodic pension, annuity (including commercial annuities), profit-sharing and stock bonus plan, or individual retirement arrangement (IRA) payments." It does the job for retirement income that Form W-4 does for wages, and since the two forms were rebuilt on the same five-step design, it looks and works like the W-4 as well. Its counterpart for a single or irregular payment, and for a lump sum that could have been rolled over, is Form W-4R.

The statute sets the default and the form adjusts it. Under section 3405(a)(1), "The payor of any periodic payment … shall withhold from such payment the amount which would be required to be withheld from such payment if such payment were a payment of wages by an employer to an employee for the appropriate payroll period." A pension is therefore withheld from the moment it starts, whether or not the retiree has done anything, and the question the form answers is how much. If no certificate is on file, the 2026 form says the payer "will withhold tax from your payments as if your filing status is single with no adjustments in Steps 2 through 4," which for a married couple with one pension usually means too much withholding, and for a household with two pensions and Social Security often too little. The form's five steps let the payee correct both: Step 1(c) sets the filing status, Step 2 accounts for a job or other pensions (including a spouse's), Step 3 claims dependent and other credits, Step 4 adds other income such as taxable Social Security or dividends, subtracts deductions above the standard deduction, and allows a flat extra amount per payment, and Step 5 is the signature.

The election not to have tax withheld is statutory. Section 3405(a)(2) provides that "An individual may elect to have paragraph (1) not apply with respect to periodic payments made to such individual. Such an election shall remain in effect until revoked by such individual." On the form it is a single box labeled "No withholding," completed with Steps 1(a), 1(b) and 5 only. Two limits attach. The form notes that a U.S. citizen or resident alien generally is not permitted to elect out on payments to be delivered outside the United States and its territories, which tracks section 3405(e)(13), and the election does not make the tax go away: the form's own caution is that too little withholding means owing tax and possibly an estimated tax penalty at filing. The payer, for its part, must tell payees about the right to elect, before or at the first payment and at least once a year afterwards.

The line between this form and Form W-4R is the shape of the payment, not its source. A periodic payment is "an annuity or similar periodic payment"; a nonperiodic distribution is anything else. Form W-4R, "Withholding Certificate for Nonperiodic Payments and Eligible Rollover Distributions," handles the other side, and its two defaults are fixed by statute rather than by wage tables: a nonperiodic distribution is withheld at 10 percent unless the payee chooses a different rate, from zero upward, while an eligible rollover distribution from an employer plan that is paid to the participant rather than sent directly to another plan is withheld at 20 percent, and the payee cannot choose less. An IRA distribution is never in that second category, so a one-time IRA withdrawal defaults to 10 percent with the right to opt out, while a monthly IRA payout is a periodic payment handled on this form. The same distinction sorts required minimum distributions: one taken as a scheduled series of installments is periodic, one taken on demand is not, and the form's rule that IRA distributions payable on demand are nonperiodic decides which certificate applies.

Practical details the form itself supplies: submit a separate certificate for each pension, annuity or other periodic payment, because each payer withholds independently; consider the IRS's estimator if the form is being completed mid-year, if payments run for only part of the year, or if there is self-employment income to cover through withholding; and note that "For payments that began before 2026, your current withholding election (or your default rate) remains in effect unless you submit a new Form W-4P." The form also tells payees to submit a new Form W-4P for other pensions if they have not updated their withholding since 2021, and a new Form W-4 for a job not updated since 2019. Nonresident aliens do not use the form at all: it says plainly "Payments to nonresident aliens and foreign estates. Do not use Form W-4P," and their withholding runs under a separate regime.

1. A periodic payment begins. A pension, annuity or IRA installment series starts, and the payer is required by section 3405(a)(1) to withhold as if the payment were wages. Before or at the first payment the payer notifies the payee of the right to elect no withholding.

2. The payee completes Form W-4P, or does not. With no form on file the payer withholds as if the payee were single with no adjustments. With a form, the payer applies the filing status in Step 1(c) and the adjustments in Steps 2 through 4 to the wage-withholding tables, or applies no withholding if that box is checked.

3. Each payer gets its own certificate. The payee files a separate W-4P with each pension or annuity, using Step 2 on the form for the highest-paying one to account for the others and for any job.

4. The election stands until changed. A certificate, including an election of no withholding, remains in effect until the payee submits a new one; payments that began before the current form keep whatever election or default was already in place.

An example of how the two certificates diverge: Raj, 62, leaves his employer with $60,000 in its 401(k) plan and takes it as a single payment made out to him rather than a direct rollover. That is an eligible rollover distribution, so Form W-4R applies and the plan must withhold 20 percent, $12,000, whatever he writes on the form; he receives $48,000 and must find the full $60,000 within 60 days to complete a rollover. Had the same $60,000 been a one-time withdrawal from his IRA instead, Form W-4R would still apply but the default would be 10 percent, $6,000, and he could elect zero. And if he had instead asked the plan for $5,000 a month for the rest of his life, that is a periodic payment: Form W-4P applies, there is no fixed percentage, and the plan withholds from each $5,000 using the wage tables for whatever filing status and adjustments he reports, or nothing at all if he checks the "No withholding" box.

Pros

• It lets a retiree set withholding on pension and annuity income with the same precision the W-4 gives wages, including a flat extra amount per payment to cover other income.
• The no-withholding election is a statutory right, useful for a retiree who would rather pay estimated tax or whose income is below the taxable threshold.
• Step 2 solves the two-pensions problem, where each payer would otherwise withhold as though its payment were the household's only income.
• It shares the W-4's design, so a person who has completed one can complete the other.

Cons

• Doing nothing is not neutral: the default treats the payee as single with no adjustments, which often withholds too much from a joint filer's pension and too little from a household with several income sources.
• Electing no withholding shifts the whole liability to estimated tax payments, and the penalty for underpaying those follows.
• Every payer needs its own form, and a change in one place (a new pension, a spouse's job ending) can require refiling with all of them.
• It does not cover lump sums or on-demand IRA withdrawals, which have their own form and, for employer-plan rollovers, a mandatory 20 percent that no form can reduce.
